Resumo: Analysis of isozymes have many applications in plant breeding specially in the study of genetic variability. Isozymes are direct product of genic expression and may help to understand the evolutionary relation between species, and allow to identify the potential genotypes for breeding programs. This work aimed to identify genetic variability through esterase polymorphism and to estimate genetic similarity among three hexaploid oat groups. Nine cultivated oat genotypes, three introductions of A. sterilis L., and 16 introductions of A. fatua L. were used. Wide polymorphisms of isozyme were observed within and between studied groups. The electrophoretic analysis showed 13 different bands with anodical migration between the genotypes. Although several bands were common for all genotypes, some of them were typical for a particular hexaploid group. These results indicate high genetic similarity between cultivated oat and A. fatua group. The A. sterilis group was more divergent, due to a more differentiated electrophoretic pattern.

O presente trabalho teve por objetivo identificar a variabilidade genética através dos polimorfismos do sistema isoenzimático esterase e estimar a similaridade genética entre três grupos hexaplóides de aveia. Para a análise foram utilizados nove genótipos cultivados de aveia, três introduções silvestres de Avena sterilis L., e dezesseis introduções silvestres de A. fatua L. Ampla variabilidade genética de polimorfismos isoenzimáticos foi observada dentro e entre os grupos avaliados. A análise eletroforética revelou treze bandas diferenciais com migração anódica entre os genótipos testados. Apesar de existirem bandas isoesterásicas comuns entre eles, algumas delas parecem ser características de determinado grupo hexaplóide. Os resultados revelaram alta similaridade genética dos genótipos cultivados com o grupo silvestre de A. fatua, enquanto que o grupo de A. sterilis foi mais divergente, pelo fato de seu padrão eletroforético ser mais diferenciado que os demais grupos.Pesquisa Agropecuaria BrasileiraPesquisa Agropecuária BrasileiraRodrigues Matiello, RodrigoFernandes Barbosa Neto, JoséJane Cruz de Melo Sereno, MariaTaderka, IvoneGirardi Pegoraro, Diego1998-06-01info:eu-repo/semantics/articleinfo:eu-repo/semantics/publishedVersionapplication/pdfhttps://seer.sct.embrapa.br/index.php/pab/article/view/4909Pesquisa Agropecuaria Brasileira; v.33, n.6, jun. 1998; 913-918Pesquisa Agropecuária Brasileira; v.33, n.6, jun. 1998; 913-9181678-39210100-104xreponame:Pesquisa Agropecuária Brasileira (Online)instname:Empresa Brasileira de Pesquisa Agropecuária (Embrapa)instacron:EMBRAPAporhttps://seer.sct.embrapa.br/index.php/pab/article/view/4909/7044info:eu-repo/semantics/openAccess2014-12-10T17:16:04Zoai:ojs.seer.sct.embrapa.br:article/4909Revistahttp://seer.sct.embrapa.br/index.php/pabPRIhttps://old.scielo.br/oai/scielo-oai.phppab@sct.embrapa.br || sct.pab@embrapa.br1678-39210100-204Xopendoar:2014-12-10T17:16:04Pesquisa Agropecuária Brasileira (Online) - Empresa Brasileira de Pesquisa Agropecuária (Embrapa)false
